Case Study of Bug Hunting: A Wild MissingNo Appeared!

Th1     Start Time : 10:30     End Time : 11:00

“There is no MissingNo.” The year was 1999, and I had called the support hotline for the Pokémon game, and this was the first thing I heard. Turns out, they were lying.

MissingNo was/is a Pokémon. A glitch, a bug, an obscure, unwanted and sometimes harmful freak that found its way into kid’s hands all over the globe. Rumour had it that this bug could randomly make or break your game completely. Needless to say: every kid tried to catch the ‘non-existent’ Pokémon number 151 to 256.

This talk is not about Pokémon. You don’t have to know anything about it. It is about a real life case that documents where real bugs live.

We’ll deep dive into the inner workings of the system, find out what made this bug possible and how it made its way to the surface. We want to explore this case and similar cases to understand about the nature of bugs, and the lessons that can be learned from them. Find out how good testers could have found and prevented these bugs through exploration and automation.

Key Takeaways:

  1. Gain deep insight into the inner workings (and failings) of a relatively easy program
  2. Find out how different systems work together in sometimes obscure ways
  3. Find out how a tester can help mitigate these vulnerabilities.
